Failure rates may be improved in application by
derating the voltage applied to the capacitor.
KEMET recommends that KO-CAPs be derated
to 90% or less of the rated voltage in application
for part types
ed to 80% or less of the rated voltage.
KO-CAPs exhibit a benign failure mode in that
they do not fail catastophically even under typical
fault conditions. If a shorted capacitor is allowed
to pass unlimited current, it may overheat and the
case may discolor. But this is distinctly different
from the “ignition” that may occur with standard
MnO2 cathode tantalums. Replacement of the
MnO2 by the polymer removes the oxygen that
fuels ignition during a failure event.
• Mil-Std-202, Method 215
Post Test Performance:
oxidize into a more resistive material that elimi-
nates the defect site in the dielectric and reduces
the flow of current.
Capacitor failure may be induced by exceeding
the rated conditions of forward DC voltage,
reverse DC voltage, surge current, power dissipa-
tion or temperature. Excessive environmental
stress, such as prolonged or high temperature
reflow processes may also trigger dielectric failure
